We calculate the contributions arising at order αs in the QCD sum rule for the spin-symmetry violating universal function χ3(v ·v′), which appears at order 1/mQ in the heavy quark expansion of meson form factors. In particular, we derive the twoloop perturbative contribution to the sum rule. Over the kinematic range accessible in B → D(∗)` ν decays, we find that χ3(v · v′) does not exceed the l...

It has been discovered recently in experiments that the dendritic integration of excitatory glutamatergic inputs and inhibitory GABAergic inputs in hippocampus CA1 pyramidal neurons obeys a simple arithmetic rule as V(S)(Exp) ≈ V(E)(Exp) + V(I)(Exp) + kV(E)(Exp) V(I)(Exp), where V(S)(Exp), V(E)(Exp) and V(I)(Exp) are the respective voltage values of the summed somatic potential, the excitatory ...

This paper argues that the existence of knowledge-intensive firms pose puzzelments for the contractual theories of the firm. For example, in knowledge-intensive firms physical assets are widely absent, the nature of employment relations and assetownership are much less clear compared to industrial firms. Although knowledge-intensive firms account for a growing share in wealth-creation and emplo...

Structure information is ubiquitous in natural scene images and it plays an important role in scene representation. In this paper, third order structure statistics (TOSS) and fourth order structure statistics (FOSS) are exploited to encode higher order structure information. Afterwards, based on the radial and normal slice of TOSS and FOSS, we propose the high order structure feature: third ord...

Complex software systems are more and more based on the abstraction of package, brought to popularity by Free and Open Source Software (FOSS) distributions. While helpful as an encapsulation layer, packages do not solve all problems of deployment and management of large software collections. In particular upgrades, which often affect several packages at once due to inter-package dependencies, o...

The use of 3D technologies in archaeology and architectural history has grown enormously. Nowadays, 3D technologies are used to record, present, analyse and reconstruct archaeological sites. Since the used tools mostly originate from other domains, the developments are characterised as technology-driven rather than methodology-driven. The recent trend of Free and Open Source Software (FOSS) and...

This study investigates the probabilistic stability of embankment slopes subjected to water level drawdown using random field finite element method (RFEM) with strength reduction technology. The shear soil properties was controlled by cohesion and internal friction angle for slope failure. were modeled a following log-normal distribution. factor safety (FOS) is calculated During numerical simul...
